摘要High-order generators of Lie algebras are defined and their basic properties are discussed in this letter. In 'classical' cases, the high-order generators are simply the enveloping algebras of Lie algebras, while, in 'quantum' cases, we can define the high-order central extensions of (infinite-dimensional) Lie algebras and can see that the high-order generators wr no longer the enveloping algebras of Lie algebras. As an example, we calculate the first-high-order central extensions of Virasoro algebras and find that the first-order and usual-order central extensions are closely related to each other.
